Description

RS-485 is the most versatile communication standard. The RS-485 standard defines the electrical characteristics of drivers and receivers for use in digital systems. The standard is published by the Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA). RS-485 signals are used in a wide range of computer and automation systems and are used in programmable logic controllers and on factory floors. Since it is differential, it resists electromagnetic interference from motors and welding equipment. It may be used to control video surveillance systems or to interconnect security control panels and devices such as access control card readers. It does not specify or recommend any communications protocol. In the next table the electrical characteristics of the standard are defined.

The RS-485 module for Arduino and Raspberry allows users to perform industrial and domotic applications. The RS-485 is the most versatile communication standard in the standard. This a standard defining the electrical characteristics of drivers and receivers for use in digital systems. It does not specify or recommend any communications protocol. In the next table the electrical characteristics of the standart are defined.

The Multiprotocol Radio Shield is an interconnection shield for Arduino, and was designed to connect two communication modules at the same time. This that means a lot of possibilities and applications can be made
using the cooking-hacks modules.

The Multiprotocol Radio Shield includes the SPI bus connections that allows the use of the RS-485 and CAN Bus modules, but also is compatible with the rest of the cooking-hacks modules as RFID, XBee and Bluetooth.

The current tutorial explains how to take the most of the Galileo board by using on it the Arduino and Raspberry Pi shields and modules designed by Cooking Hacks

Galileo comes with a single-core 32-bit, 400MHz Quark SoC X1000 processor, supports 3.3 or 5 volt shields and has an Ethernet and USB port. Compatible with Windows, Mac OS and Linux, the software of Galileo also has support for the Arduino shield ecosystem.
